Abstract

The utility model relates to a bamboo and wood composite container bottom plate with an improved bamboo curtain as a surface layer, which comprises a layer of improved bamboo curtain, 2-3 layers of bamboo curtains inward (or wood veneer is adopted to replace the bamboo curtain), a layer of horizontal texture wood veneer and a layer of bamboo curtain and a layer of veneer spaced inward (or all can be wood veneers), wherein the textures of the middle three layers are all longitudinal. A layer of phenolic impregnated materials is adopted for the outermost layer. The manufacturing method includes steps as follows: double-face gluing, aging or low-temperature drying the wood veneer with moisture content less than or equal to 10%; and assembling the veneer, the bamboo curtain and the impregnated paper and hot-pressing at the temperature of 130-150 DEG C and under the maximum pressure of 2.0-3.5 MPa. The bamboo and wood composite container bottom plate has the advantages that the surface layer is the improved bamboo curtain formed through splicing equal-width thin bamboo sheets, the produced container bottom plate has attractive appearance, wear resistance and stable quality, and the strength and modulus of elasticity can meet the technical requirements of the international container industry.

Description

A kind of is the bamboo wood composite container baseboard on top layer to improve bamboo curtain splint
Technical field
The utility model relates to a kind of is the bamboo wood composite container baseboard on top layer to improve bamboo curtain splint, belongs to the wood-based plate manufacturing technology field in the timber industry.
Background technology
The main loaded area of container is a base plate, and container manufacture requires base plate to have very high mechanical property, presentation quality, impact resistance and ageing-resistant performance.Existing bamboo wood composite container baseboard has two kinds of forms: patent ZL 98111153.x mesexine is a kind of bamboo wood composite container baseboard that impregnated paper adds bamboo mat; Another patent ZL 03152841.4 mesexine is the high-density bamboo material thin layer that hot pressing forms through high pressure, uses it to be composited as the core secondary hot pressing with structural particleboard or board using poplar board etc. as the table backing layer then again.First kind in order to obtain beautiful appearance, needs impregnated paper and bamboo mat, and the bamboo mat braiding needs more cost of labor, and the surface quality of base plate is not high; Though a kind of mechanical property and the acceptable outward appearance of also meeting the requirements of in back owing to be post forming, also needs its cemented surface sanding and gluing, it is compound to pass through secondary hot pressing again, has consumed the more energy, material and labour.All there are problems such as cost height in these two kinds of bamboo wood composite container baseboards, and case east is difficult to accept.
Summary of the invention
It is the bamboo wood composite container baseboard and the manufacturing approach on top layer to improve bamboo curtain splint that the utility model provides a kind of; Its objective is and utilize the improvement bamboo curtain splint to be the top layer; Through wide thin bamboo plate and novel connecting method, can obtain the less surface layer of surface gaps, through the phenolic impregnated material of compound one deck color even; Make and have color even wear-resisting again surface layer attractive in appearance, fine and close, the composite bottom board of bamboo wood high-intensity performance is arranged again.
The technical solution of the utility model: it is characterized in that from outside to inside to being called one deck hard paper, one deck improvement bamboo curtain splint, two-layer vertical texture bamboo curtain splint; Again inwardly for cross grain veneer and vertical texture veneer are spaced (intermediate layer be vertical texture veneer except), totally 13 layers, in the middle of three layers be vertical texture, remaining is then by a cross grain veneer and the alternate laying of a vertical texture veneer.
Described improvement bamboo curtain splint is that the bamboo bar is processed into wide thin bamboo plate through special equipment, after the drying it is processed than small gaps with line, thin bamboo plate, thin veneer, nonwoven etc.
The phenolic impregnated material can be impregnated paper, also can be immersion non-woven fabrics, also can be dipping glass cloth.
The advantage of the utility model: can effectively utilize China and timber all over the world, like various softwoods, the broadleaf timber of wildwood and artificial forest, and have that growth is fast, the cycle lack, can cut selectively every year, bamboo timber resource that the sustainable utilization time is grown.With the compound use of these materials, through scientific design and reasonably combination, both can solve the difficulty of hardwood resource scarcity in the world wide, can solve the technical barrier of the novel base plate of producing to meet the requirement of trans-container industrial technology in enormous quantities again.Use through the closely knit improvement bamboo curtain splint in surface simultaneously, change the bamboo mat of purchasing into oneself customize improvement bamboo curtain splint, surface quality of products and stability increase.
The present invention is woven into bamboo curtain splint (or will piece together tight bamboo chip glue jail with several veneer veneers etc.) with special wide bamboo chip, again through being composited with bamboo curtain splint, veneer.All should add pesticide in the used glue, uniformly penetrating is in the surface material of container bottom board when hot pressing to make it, and base plate has long-acting insect protected performance like this; Core material and surface material are combined into slab, process container bottom board through hot-press gluing again, each item performance indications such as its intensity, elastic modelling quantity, surface quality can both meet the specification requirement of trans-container industry fully.
